Take a look at the 12992-90001_loaderRomsApr86.pdf doc on Al's site. It has
details of the operation of the various HP 1000 loader ROMs, including
source code listings.
There is a separate ROM, p/n 12992-80007 12992E, which is specifically for
booting from the 9885 flexible disk. I'm not sure what interface is used to
the 9885 for that loader ROM.
ROM p/n 12992-80002 12992B is for MAC 7905/7920 drives, 13175A/B interface.
ROM p/n 12992-80004 12992H is for HP-IB 7920H/7925H/9895 drives, 12821A
interface.
If you remove the memory cards from the front card cage of the 1000E CPU you
should be able to see the loader ROMs and if you can read the p/n labels you
should be able to reference those back to the loader ROM doc to see exactly
what you have.
>I know that a lot of the older HP floppy drives (9885, 82901/902, 9121,

>1000 can boot from one of those floppy drives.
